I don't understand what your equation means. You can't have an expression like m - dm, that is, you can't additively combine scalars with differentials. They exist in different spaces.
Maybe you mean:
dv = [K/(m - (dm/dv))] dm ?
Then rewrite it as
(dv/dm) [m - (dm/dv)] = K
m(dv/dm) - 1 = K
dv/dm = (K+1)/m
v = -(K+1)/(m**2) + constant
But I am guessing your intentions, and I might be missing something.

I'm new on scipy (and new with numerical methods), so excuse me if you found trivial my question, but I spent time searching for an answer. Well, the problem:
I want to integrate this equation:
dv = [K/(m-dm)] dm
where where d means differential (of course). dm is in the numerator and denominator.
-Is there chance to solve this integral analytically?
-how can I use scipy to integrate this equation (knowh the initial values)?
